If the original box is not listed for this purpose, it must be retrofitted and attached securely to the building structure. But what you really have to be careful of is to make sure the electrical box that the light fixture is attached to will support the extra weight of the ceiling fan. They are used most commonly for ceiling- or wall-mounted light fixtures that weigh no more than 50 pounds. These are shallow electrical boxes with only enough space for fitting two or three electrical connections.
Ceiling fans can be too big for a room, resulting in low airflow and less cooling. However, ceiling fans can also be too small, which creates too much airflow. Some tips for sizing your ceiling fan include measuring the longest wall, measuring floor-to-ceiling, and considering light kits. The ALA recommends a to inch fan for a room up to 75 square feet, such as a bathroom; a to inch fan for a medium-size room up to square feet; and a to inch fan for a room around square feet; and inch or larger fans are available for larger spaces.
The most common method used to find the right downrod length is to take the ceiling height, subtract the height of the ceiling fan most fans are between 12 and 18 inches in height depending on the fan , and then subtract the desired hanging height usually eight feet.

Press the flat edge of the feet against the ceiling then center the shaft above the hole.
Rotate the shaft to fasten the brace onto the framing. Snap the metal saddle over the shaft so it is centered over the hole. Insert the existing wire into the cable clamp at the top of the new metal box. Slide the box above the saddle screws.
Secure the nuts to fasten the box onto the shaft using either a nut driver or a deep-well socket. Tuck a loop of grounding wire about three-quarters around the grounding screw then tighten the screw. Place the hanger bracket with its opening on the uphill side of the sloped ceiling. Using the appropriate screws provided with the fan brace, screw the hanger bracket into the box. Position the motor right side up. Insert the wire through the downrod, then attach this into the mounting collar.
Slide the downrod pin inside the collar and tube. Use the cotter pin to lock this into place. Tighten the locknuts and screws firmly. Slide the collar cover followed by the canopy over the downrod.
Slip the ball over the downrod then push the pin into both sets of holes. Lift the ball above the pin then tighten the set screw. Raise the assembly above the open side of the bracket and then lower it into place. Wind the motor until the ball slot is locked into place above the tab on the bracket. Join the bare ground wire from the box onto the green ground wire on the bracket using a wire connector.
Use spacers if necessary to level. After mounting, pull down on the base to be certain the mounted base will support the weight of the fan while running. Attach the fan mount to the fan motor. Because this is a flush mount, leave out the hanging tube. Hang the fan motor on the base there will be a hook provided while connecting the wires from the fan motor to the wires in the box. It may be necessary to shorten the wires from the fan motor. Don't cut them too short, though; allow about six inches of extra wire to give yourself some working room.
Connect the black wire for the fan motor and the blue wire for the lights together on the black wire from the box. Use the wiring nuts provided in the kit to firmly make and insulate this connection.
Connect the white wire from the fan to the white wire from the box with a second wire nut. Attach the green ground wire to the ground wire in the box. This may be a bare wire, or a green insulated wire. Install the fan mount to the base mount by sliding the slotted holes onto the screws in the side of the base.
Turn the fan motor to lock the base and fan mount together. There will be four screws.
